What kind of parameter is the power factor? It can directly affect the calculation of electricity bills! Let us first look at the electricity company's calculation method for the electricity price of industrial users:
Total electricity bill = active electricity tariff + basic electricity fee + power factor adjustment electricity fee
It can be seen that the power factor has a place in the formula. Now we will introduce the power factor. The power factor is equal to the ratio of active power to apparent power. It reflects the utilization rate of power equipment. This may be too vague, I will give Let us give you an example. Let's look at this picture. From this picture, we can easily understand that the power factor is equivalent to the actual proportion of beer in the glass. The same reason, the power factor is the ratio of the power used to the apparent power. .
That is to say, the power factor is closely related to the active power and the reactive power. The active power is better understood and the useful work is done. How does the reactive power understand? Everyone will look at this picture again. In the process of moving forward, only the thrust is doing work, the support is not doing work, but there is no support, the car can't move forward, and the thrust can't achieve work. This is not difficult to understand, reactive power is an important condition for maintaining working power in some occasions.
In practical life applications, reactive power is generated as long as there is an inductive load or a capacitive load. The electrical loads in the power grid, such as motors, transformers, fluorescent lamps, and electric arc furnaces, are mostly inductive loads. These inductive devices In the operation process, it is not only necessary to absorb the active power to the power system, but also absorb the reactive power. In addition, any converter capable of storing and releasing energy can also generate reactive power. If the reactive power is too large, the power factor will be too low and it will be fined.
How to do it? At this time, we need to perform reactive power compensation. The purpose of reactive power compensation and energy saving effect is to reduce load current and reduce line loss; improve power factor and reduce power consumption.
Therefore, after installing the parallel capacitor reactive power compensation device in the power grid, it can provide the reactive power consumed by the inductive load, and reduce the reactive power supply of the power supply side and the reactive power delivered by the line. Since the flow of reactive power in the power grid is reduced, the power loss caused by the transmission of reactive power in the transformer and the busbar in the transmission and distribution line can be reduced, which is the benefit of reactive power compensation. The main purpose of reactive power compensation is to increase the power factor of the compensation system. Because the electricity sent by the power supply bureau is calculated by kVA or MVA, but the charge is charged in kW, which is the actual work done. There is a difference between the two, which is generally the difference. Reactive power in kvar.
The domestic ZLG Zhiyuan Electronics EAS630 energy efficiency analyzer can effectively measure the power factor of the line and help the enterprise and industrial users to complete the reactive power compensation in time. Users can adopt appropriate treatment schemes for different test results to improve the energy utilization rate. Reduce equipment failure rate and reduce production costs.
